Bringing Us Back to His Likeness

Hitherto the Word, in whose image humanity had been made, was invisible, and for that reason humanity easily lost the likeness. When, however, the Word of God had been made flesh, he realised both. For on the one hand, he revealed the true image, himself becoming that which was his own image; on the other hand, by realising the likeness he restored it, making humanity similar to the invisible Father through the visible Word.
